Start-up (E)
When the unit is used for the first time
or after a long period of disuse, smoke or
odour may result from dust or dirt that has
collected on the element. This is completely
normal and disappears after a short time.
Adjustment of the air curtain and air flow
The direction and speed of the air flow
should be adjusted considering the load on
the opening. Pressure forces affect the air
stream and make it bend inwards into the
premises (when the premises are heated and
the outdoor air is cold).
The air stream should therefore be directed
outwards to withstand the load. Generally
speaking, the higher the load, the greater the
angle that is needed.
Connecting the water coil (W)
The installation must be carried out by an
authorised installer.
The water coil has copper tubes with
aluminium fins and is suitable for connection
to a closed water heating system. The heating
coil must not be connected to a mains
pressure water system or an open water
system.
Note that the unit shall be preceded by a
regulating valve, see Frico valve kit.
When mounting vertically the water
connection can be done from above or below,
according to ordering key, with connecting
DN25 (1"), inside thread. When mounting
horizontally the water connections can be
done from the right or left top, according to
ordering key, with connecting DN20 (3/4"),
inside thread. Flexible hoses are available as
accessories, see accessories pages.
NOTE: Care must be taken when connecting
the pipes. Use a wrench or similar to hold the
air curtain connections to prevent straining
Basic setting fan speed
The fan speed when the door is open is set
using the control. Note that the air flow
direction and fan speed may need fine
adjustment depending on the loading of the
door.
Filter (W)
The distance between the coil plates in
combination with the hole diameter of
the intake grille protects against dirt and
blockage. This normally makes a separate
filter unnecessary.
Service, repairs and maintenance
For all service, repair and maintenance first
carry out the following:
1. Disconnect the power supply.
2. The front plate/service hatch is opened by
unscrew the screws in the side of the unit/
upper side.
Maintenance
Unit with water heating:The intake grille
should be cleaned regularly to ensure the
air curtain effect and the heat emission
from the device. How often depends on local
circumstances. A clogged grille is not a risk,
but the appliance function can fail. Vacuum
the intake grille regularly from outside when
dust is visible, for example as a part of the
cleaning routine.

of the pipes and subsequent water leakage
during connection to water supply pipe-work.
The connections to the heating coil must
be equipped with shut off valves to allow
problem free removal. A vent valve should be
connected at a high point in the pipe system.
and power supply for heat (400V3~) should
be connected to a terminal block. For units
with electrical heating, power and control
should be supplied separately.
The largest cable diameter for the terminal
block is 16 mm². The cable glands used must
meet the protection class requirements. In
the distribution board it is to be indicated
that ”the air curtains can be supplied from
more than one connection”.
See wiring diagrams.
*) Dimensioning of external wiring shall comply with
applicable regulations and local deviations may occur.
